IMPROVEMENT IN PLOW AND SUBSOILER.

The Schedule xjeferred to in these .Letters .Patent Vand. making part ofthe sama.

To all whom 'it 'ma/y Vconcern Be it known that I, GAIN ROBINSON, ofPlymouth, in the county of Richland, and State of Ohio, have invented acertain new and useful Improvement in Plows and I do hereby 'declarcthatthe following is a full and complete description of the construction andoperation of the same, reference being. had' tothe accompanyingdifferent views.

In this invention, the object attained is thecombination .of a subSoil-plow with au ordinary surface-soil plow,rthereby4 producing, inone implement, the combined action and advantagev of both, at a muchless expense than two separatevplows, and not greatly exceeding the costof one.

In iig. l, A represents, the plow, of which'A Vis the beam, B, themould-board, O, the share, and D, the handles, all of which are orma-ybe constructed in the ordinary way.

To said plow isattached the subsoiler, or plow, E,

directly lin the rear ofthe plow, by means of 'the curved y beam F, theinner en d being secured tothe upright bolt G, figll, by the strapsH,'between which the end of the beam is pivoted, thereby allowing to ita vertiticalinovement.

i I is a lever, the lower end of which is bifurcated. Theend of eachbifurcation is pivotedto the handles D, as shown in g. 2, the purpose ofwhich'will hereinafterbe shown. 4

vThe beam F referred to,l is connected to the lever I, by means of thelink J ,whereby it may be elevated above the ground by means of saidlever, and is thus secured by the'spring'K.

' Said spring, on elevating the lever, catches upon the brace L, andthus supports the Vsubsoil-plow out of the furrowwhile the surfaceplowonly may be f n operation.

As above observed, the special purpose of this .plow is to perform thesurface-soiling and subsoiling at one operation, thereby saving the.expense of two plows for the performance of the work.

' The ordinary practice pursued in this kind of work V is to follow thesurface-plow with the subsoil, which not' only requires a double team,but also a man to each team and plow; whereas, in combining the twoplows in one, as above described, one tea'm' onlyis required to do thework, and the plowingcan be efectually performedby one person, insteadof two, as required when done in the ordinary way.

When desired to use the plow without the subsoiler, the latter can ^beeasily detached, or raised up out. of

the way, by means of the lever I, which, on throwing itforward, asindicated by the dotted lines a., fig.- 1, will draw upward the ,beamand plow E F." -I n this condition, the surface-plow can be used for allordinary surface-work as a common pl.^,w

It will be observed that the landside of. the plow is double, it beingprovided with a false side, A', fig. 3, a side view of which is showniug. 4, Vand ofA which fig. 5 is an under-side view.;

This false side is secured to the plow by means of .the'hooks B',projecting from the false side, and inserted in `slots b, lig. 1, madein the true side of the plow.

. The falsesid'e is put on before the share O issecured .in place, andthereby prevents the side from I working frontward, as the front end ofthe side abntsagainst the share. By this means', the side is rmlyf andsecurely attached'to the plow, without theraidof -bolts -or keys.

. I am aware that false -landsides are iused, but this I do not claim;but that ,which-I doclaim is'the peculiar manner of attaching the'.sides tothe plow, which, ascrdinar'ily done, is` by the means of bolts,which I dispense with by the use of the morepsimple and less expensivehooks referred to.'

What I claim asmy invention, and desire to secure by Letters Patent, is-

1. The plow E, beam F, links'J,and spring-K, as

arranged, and operated by the lever I, iu combination withthe lplow A,substantially as and for the purpose set forth... A Y

2. Attaching the false laudside Alto the plow, by means of the hooks B',substantially as specied. GAIN ROBINSON. Witnesses:
